The Ultimate guide to DevOps Tools Part #1 : Docker hereTalking about docker concept , how install it.The Ultimate guide to DevOps Tools Part #2 : Docker herehow to build your first application using dockerIn this post i will talk about Docker Services.
as already mentioned above this post i will describe the level up about docker which is services which mean scale the application and enable load-balancing. When i will need to create a services ?
Regarding to Docker Documentation here
To deploy an application image when Docker Engine is in swarm mode, you create a service. Frequently a service is the image for a microservice within the context of some larger application. Examples of services might include an HTTP server, a database, or any other type of executable program that you wish to run in a distributed environment.
But First Let's Understand what is the docker services ?
Simply It's group of containers of the sam…

This article will continue the basic for docker which is consider one of the DevOps Tools after finishing these series i will choose another tools that could help DBA to automate their works.

In this post i will show you how to build your first application using docker, without docker if you need to programming using language first you should install that language on your PC and test it on your development environment and for sure the production should be ready to sync and test your code again on it seems a lot of work.😥

But now with docker you just pull/grab that image, no installation needed, and run your code on that image.🎉

But how we can control what happening inside the environment, like Accessing to resources like networking interfaces and disk drives is virtualized inside this environment which is isolated from the rest of your system all of this happening by something called Dockerfile.

I will try to cover the Docker basics in different posts to allow people and reader understand more about this tools, also i will provide reference in each of the posts in case you need more information:-

Set up your Docker environmentBuild an image and run it as one containerScale your app to run multiple containersDistribute your app across a clusterStack services by adding a backend databaseDeploy your app to productionDocker Concept:-
To Understand docker more you can imagine or can been seen as computer inside your current computer, the most cool thing about docker is that you will not even feel that there is another computer running inside your computer and share the same resource of your computer, include to that if you friend ask for the same container all you have to do is send it to them and they will have the same output for anything running at this container. Why Should i use docker when there are similar solution :- Very simple to configure.Docker provides this same capabi…

Cloning is the process of copying an existing entity to a different location while preserving its state. Some situations in which cloning Oracle Fusion Middleware is useful are:

Creating a Middleware home or Oracle home that is a copy of a production, test, or development environment. Cloning enables you to create a new Middleware home or an Oracle home with all patches applied to it in a single step. This is in contrast to separately installing, configuring and applying any patches to separate Oracle homes.Preparing a "gold" image of a patched home and deploying it to many hosts.
When you move a Middleware home, you create an archive of the source Middleware home and use the archive to create the copy of the Middleware home: ./copyBinary.sh -javaHome /u01/jdk -archiveLoc /u01/test.jar -sourceOracleHomeLoc /u01/Oracle/Middleware/fmw_soa
After this copy the jar file to new location and run the following command :- ./pasteBinary.sh -javaHome /u01/jdk -archiveLoc /u01/test.jar -t…

I wrote this article because there is no much information about this product to configure it as cluster so i choose to write it step by step to help people around the world in case they need information about this product.

this article is fully details and working on Solaris but the same steps could be follow for Unix/Linux and windows.
